- AIM: Managing type 1 diabetes mellitus requires efficient cognitive and executive skills, and adolescents who have attention-deficit/hyperactivity disorder (ADHD) may face specific challenges. This study explored young people's experiences of diabetes treatment and care.METHOD: In a population-based study, comprising 175 patients aged 5-16 years with type 1 diabetes mellitus in two Swedish counties, we found that eight also met criteria for ADHD. Six of these, aged 14.5-16 years, participated 2013-2014 in interviews that targeted aspects of their diabetes treatment. Conducted by two psychologists, these used the inductive qualitative, semi-structured interview format.RESULTS: The two boys and four girls all reported difficulties in creating routines for their diabetes treatment and that problems were aggravated during stress. They had been criticised by their parents and the diabetes team when their blood levels indicated inadequate diabetes control. They requested ongoing information, involvement of their friends, group meetings and easy access to the healthcare system during difficult times.CONCLUSION: Patients with type 1 diabetes mellitus and concomitant ADHD faced problems with their diabetes management, especially during stressful situations. Diabetes care provision should pay particular attention to patients with co-existing neuropsychiatric and neurodevelopmental disorders such as ADHD.

- The incidence rate of tonsillar cancer is increasing worldwide. The current study identifies a parallel increase in the incidence of tonsillar cancer, human papilloma virus (HPV) and p16 expression among a population from northern Sweden, a sparsely populated area, confirming the strong association between p16 and HPV infection in tonsillar tissue. Data from the Swedish Cancer Registry was assessed to identify cases of tonsillar cancer in the northern territorial area of Sweden. HPV DNA was extracted from paraffin embedded diagnostic biopsies and detected by polymerase chain reaction using general primers Gp5+/6+ and CpI/IIG. Expression of p16 was identified by immunochemistry. Patients were grouped into urban or rural residence categories. A total of 214 cases were identified, comprising 155 (72.4%) men and 59 (27.6%) women, and 65 of these patients, who presented between 2000 and 2012, were analyzed. The overall median age for the analyzed patients was 58 years; 48 (74%) were males (median age, 57.5 years) and 17 (26%) were females (median age, 65 years). Of the 65 specimens, 59 (91%) were positive for HPV, and 62 (95%) expressed p16. The incidence of tonsillar cancer in the cohort demonstrated a 2-fold increase between 1990 and 2013; specifically, a 2.7-fold increase was observed in men whilst the female group exhibited only a small increase. These findings demonstrate a strong association between p16 expression and HPV infection in tonsillar malignancies. The incidence of HPV-positive tonsillar cancer has increased in recent years, even in sparsely populated regions, as demonstrated in northern Sweden.

Journal article (peer-reviewed)abstract
- AIM: This paper summarised national data on the prevalence of overweight and obesity among 4-year-old children in Sweden in 2020, the first year of the COVID-19 pandemic. It compares this with data from 2018. Differences between regions and sex were identified.METHODS: Comparative data from Swedish Child Health Services were available for 18/21 regions. Chi-square tests were used to compare data from 2018 and 2020 and to examine differences between the sexes. Sex and year were examined through interaction tests.RESULTS: In 2020, 13.3% of the 100 001 children had overweight or obesity: 15.1% of the girls and 11.6% of the boys (p < 0.001). In 2018, 11.4% of the 105 445 children had overweight or obesity: 13.2% of the girls and 9.4% of the boys. This was an overall increase of 16.6% (p = 0.000) in the national Swedish data from 2018 to 2020. The increase between the years was greater for obesity (31.8%, p = 0.000) than for overweight (13.3%, p = 0.000).CONCLUSION: The prevalence of overweight and obesity among 4-year-olds in Sweden increased during the COVID-19 pandemic and needs to be addressed. The prevalence needs to be followed as part of prevention programmes and to evaluate health interventions.

In: Acta paediatrica (Oslo, Norway : 1992). - : Wiley. - 1651-2227 .- 0803-5253. ; 102:4, s. 410-415

Journal article (peer-reviewed)abstract
- AIM: To examine the association between neurodevelopmental problems and high HbA1c among paediatric patients with type 1 diabetes. METHODS: A population-based study was performed among patients with type 1 diabetes (5-16 years) in two Swedish counties (n=233). The Five to Fifteen (FTF) questionnaire targeted neurodevelopmental qualities. Scores above the 90(th) percentile in the various domains are considered as definitive problems and scores above the 75(th) percentile as mild. FTF-scores were compared with regard to HbA1c ≤73 mmol/mol and >73 mmol/mol (8.0%). RESULTS: The response rate was 190 (82%). Neurodevelopmental problems were not over-represented among patients in general. Memory and learning problems were associated with HbA1c >73 mmol/mol (p = 0.01). This correlation was especially seen in adolescents (12-16 years) where mild executive problems (adjOR 3.1), definite memory problems (adjOR 5.0) and definite learning problems (adjOR 5.0) were associated with HbA1c >73 mmol/mol after adjustment for gender, diabetes duration and age of onset. CONCLUSION: Our findings that high HbA1c are more common in adolescent diabetes patients with neurodevelopmental problems generate the hypothesis that these problems might precede poor metabolic control. If so, early detection of neurodevelopmental problems would allow individually tailored treatment that may improve metabolic control and prevent complications.

Other publication (other academic/artistic)abstract
- Management of diabetes is demanding and requires efficient cognitive skills, especially in the domain of executive functioning. However, the impact of impaired executive functions on diabetes control has only been studied to a limited extent.Objective: To investigate the association between executive dysfunctions and diabetes control in adolescents with type 1 diabetes.Research design and methods: 241/477 (51 %) of 12-18 year-old adolescents, with a diabetes duration of >2 years, in Stockholm. Uppsala and Jönköping participated. Parents and adolescents completed questionnaires, including BRIEF, ADHD Rating Scale (ADHD-RS) and background factors. Diabetes related data was collected from the Swedish Childhood Diabetes Registry, SWEDIABKIDS. Self-rated and parent-rated executive functioning problems were analyzed with regard to gender, HbA1c, frequency of outpatient visits and physical activity, taking background factors into account.Results: Executive functioning problems, according to BRIEF and/or ADHD-RS, respectively, were associated with mean HbA1c > 70 mmol/mol, many outpatient visits and low physical activity for both genders. Self-rated executive problems were more prevalent in girls, while parents reported these problems to a larger extent in boys.Conclusion: Patients with executive functioning problems need to be recognized by the diabetes team. The diabetes care should be especially tailored to provide adequate support to these patients.

Journal article (peer-reviewed)abstract
- Background: Managing modern diabetes treatment requires efficient executive functions. Patients with attention-deficit/hyperactivity disorder (ADHD) and type 1 diabetes have poor metabolic control and present with ketoacidosis more often than patients without ADHD. Objective: To assess whether patients with type 1 diabetes and with indications of executive problems met criteria for ADHD, and to investigate whether these patients had difficulties achieving metabolic control. Methods: In a hospital-based study, including 3 pediatric departments at hospitals in Stockholm and Uppsala, Sweden, questionnaires regarding executive problems had been filled out by 12- to 18-year-old patients with type 1 diabetes and their parents. Out of 166 patients with completed questionnaires, 49 were selected for a clinical study due to reported executive problems/ADHD symptoms. However, 7 already had a diagnosis of ADHD, 21 denied follow-up, 8 did not respond, leaving 13 adolescents for the clinical assessment. Results: Of the clinically assessed adolescents, 9 (6 girls) met criteria for ADHD. Patients who did not respond to the follow-up and patients who were diagnosed with ADHD within the study, showed to a larger extent than the other study groups high HbA1c levels (>70 mmol/mol, 8,6%). HbA1c >70 mmol/mol (8.6%) was associated with diagnosed ADHD (prior to or within the study), odds ratio 2.96 (95% confidence interval 1.02-8.60). Conclusion: Patients with type 1 diabetes and poor metabolic control should be assessed with regard to ADHD. There is a need for paying special attention to girls with poor metabolic control.

Protective factors, health-risk behaviours and the impact of coexisting ADHD among adolescents with diabetes and other chronic conditions
- 2016
-
Doctoral thesis (other academic/artistic)abstract
- Mental health problems are increasing in Swedish adolescents and mortality rates are higher in this age group than among younger. 10-20% of all adolescents suffer from a chronic medical condition (CC). Few protective factors (PF) and clustering of health-risk behaviours (HRB) are frequent among adolescents with CCs.One of the most common CC in Swedish adolescents is type 1 diabetes mellitus (T1DM). Metabolic control often deteriorates during adolescence, especially in girls. Poor metabolic control is associated with increased risk for long-term complications, of which cognitive problems are common. However, the implication of cognitive/executive problems in patients with T1DM has not been sufficiently studied. Neither has the impact of neurodevelopmental problems (NDP), such as ADHD, on HRB in adolescents with CCs been analysed.Methods: In paper I and II the questionnaire ”Life and Health in Youth” was distributed to all students in year nine and year two of the upper secondary school in the county of Sörmland, 2008 (n=5771) and 2011 (n=5550). Adolescents with CCs were compared to healthy peers with regard to PFs and HRBs. In paper III, the ”Five to Fifteen” questionnaire was used in 175 paediatric patients with T1DM. Patients with indications of NDPs were compared with patients without such problems with regard to metabolic control. In paper IV, the BRIEF questionnaire and the ADHD Rating Scale as well as data from the Swedish Childhood Diabetes Registry was used in 241 adolescents with T1DM. Patients with indications of executive problems were compared with patients without such problems with regard to diabetes control.Results: CCs were associated with few PFs and clustered HRBs. The combination of CCs and low numbers of PFs was found to be associated with an increased risk of clustered HRBs. In the presence of coexisting ADHD the pattern of few PFs and clustering of HRBs was aggravated. ADHD was more common among adolescents with other CCs.Definite memory and learning problems as well as mild executive problems were associated with poor metabolic control, especially among adolescents. Executive problems were also associated with many outpatient visits and low physical activity. Girls with T1DM tended to self-report executive problems to a larger extent than boys, while parents more often reported these problems in boys.Conclusion: Knowledge about factors influencing treatment adherence and life in general is essential in the work with chronically ill adolescents. Focus must be put on enhancing PFs in order to avoid HRBs. Identification of coexisting NDPs, such as ADHD, is crucial, since such problems can adversely influence treatment adherence, HRBs and school achievements

Journal article (peer-reviewed)abstract
- BACKGROUND: Management of diabetes is demanding and requires efficient cognitive skills, especially in the domain of executive functioning. However, the impact of impaired executive functions on diabetes control has been studied to a limited extent. The aim of the study is to investigate the association between executive problems and diabetes control in adolescents with type 1 diabetes.MATERIALS AND METHODS: Two hundred and forty-one of 477 (51%) of 12- to 18-year-old adolescents, with a diabetes duration of >2 years in Stockholm, Uppsala, and Jönköping participated. Parents and adolescents completed questionnaires, including Behavioral Rating Inventory of Executive Function (BRIEF), Attention-Deficit/Hyperactivity Disorder (ADHD)-Rating Scale (ADHD-RS) and demographic background factors. Diabetes-related data were collected from the Swedish Childhood Diabetes Registry, SWEDIABKIDS. Self-rated and parent-rated executive problems were analyzed with regard to gender, glycosylated hemoglobin (HbA1c), frequency of outpatient visits, and physical activity, using chi-square tests or Fisher's test, where P-values <.05 were considered significant. Furthermore, adjusted logistic regressions were performed with executive problems as independent variable.RESULTS: Executive problems, according to BRIEF and/or ADHD-RS were for both genders associated with mean HbA1c >70 mmol/mol (patient rating P = .000, parent rating P = .017), a large number of outpatient visits (parent rating P = .015), and low physical activity (patient rating P = .000, parent rating P = .025). Self-rated executive problems were more prevalent in girls (P = .032), while parents reported these problems to a larger extent in boys (P = .028).CONCLUSION: Executive problems are related to poor metabolic control in adolescents with type 1 diabetes. Patients with executive problems need to be recognized by the diabetes team and the diabetes care should be organized to provide adequate support for these patients.

Journal article (peer-reviewed)abstract
- AIM: This study aimed to measure protective factors and risk behaviour among adolescents with chronic conditions (CCs) and to evaluate the impact of protective factors on risk-taking.METHODS: A population-based study of 7262 students aged 15 and 17 years old was performed in Sörmland, Sweden 2008 (response rate 82%). The questionnaire explored background factors, CCs, risk behaviours and protective factors. CCs were reported by 8%, while 58% had no health problems.RESULTS: Girls with CCs encompassed less individual protective factors, while boys with CCs tended to over-report all individual risk behaviours compared with healthy peers. Both boys and girls with CCs were more likely to report few protective factors and co-occurrence of risk behaviours. The adjOR for clustered health risk behaviours was 1.6 (1.0-2.5) in youths with CCs and ≥4 protective factors and 6.3 (3.6-10.9) in youths with CCs and 0-3 protective factors, as compared to healthy peers with ≥4 protective factors.CONCLUSION: Adolescents with CCs reported fewer protective factors and more risk behaviours than their healthy peers. The vulnerability of adolescents with CCs and few protective factors is important to acknowledge. Professionals should provide stronger protection for these adolescents, to prevent risky behaviour.
